FYI, I too have have DTMF not recognized most of the time since 1.6.2 dated Sep 2015. I cannot upgrade to the latest version due to pending fixes. I am on Callcentric and about 90 percent of the time DTMF is not recognized. I was going to wait for the next 1.6 update and see if that helps. I also have a flooding of TCP ports but don’t think it’s related.
